GEORGE E. CRANE, OF EAST SOMERVILLE, MASSACHUSETTS.

BOX-FASTENER.

SPECIFICATION forming part of Letters Patent No. 256,823, dated April25, 1882,

Application filed March 10, 1882.

(No model.)

To all who 1n it may concern Be it known that I, GEORGE E. CRANE, ofEast Somerville, Middlesex county, and State of Massachusetts, haveinvented a new and useful Fastening for Tubs or Boxes, of which thefollowing is a specification.

My invention more particularly relates to fastenings for tubs used toship oysters in, which are, after being closed, secured by a wirefastened with a lead seal, so that they cannot be opened withoutdestroying such sealing device.

The object of my invention is to provide a fastening device which willfirmly hold the top in place without dangerot' displacement when thesealing-wire is not used, but which will in no way prevent its use whenrequired. 1 accomplish these objects by the mechanism illustrated in theaccompanying drawings, in

which-- Figure l is a perspective of my fastening device; Figs. 2 and 3,modifications of the same. Fig. 4 is a view showing a part of anoystertub with my device in position.

A is the tub, provided with a cover, 13. O is a fastening bar, which ishinged or hooked at one side of the tub, and carried across the cover tothe other, where a hasp, D, is hooked upon it. This hasp is providedwith slots 01 01, into which the staplef, fixed upon that side of thetub,enters. Upon the tonguejof the hasp which enters the staple is alip, e, which pro-. jects at right angles to the face of-the hasp, andwhich is of such length and shape that it will just pass under the topof the staple when the hasp is borne down close to the surface of thetub, after which, if the hasp be allowed to spring away from the tub,the lip will prevent the tongue from being withdrawn from the staple,and the hasp cannot therefore become disconnected from the staple. Thehaspis also provided with another lip, 0 which is formed of a part whichdoes not pass through the staple. These two lips, 13 and 0 are providedwith openings 70 it, through which a wire may be passed, which, havingits ends sealed together,will prevent the unfastenin g of the hasp untilthe wire is broken. The lower lip also serves as a convenientthumb-piece to move the hasp sidewise as its tongue passes under thestaple when being fastened or unfastened.

The slots cl (1 may, if desired, have an up ward inclination as theyenter the hasp, so that as the legs of the staple enter the slots andthe hasp is moved sidewise, the hasp will be drawn down,,bringing thebar 0 with it, and thereby bearing the cover firmly into place. Whensuch inclination is given to the slots in the hasp the horizontal partof the slot may be ended next the inclined part with a shoulder, whichwill prevent the hasp from slipping out ofthe staple. v

To still further guard against the accidental displacement of the haspwhen no wire and seal are used at'terthe parts are put togetheras, forinstance, when the empty tubs are being returned-I connect the hasp tothe bar, so that it will be necessary to spring the hasp over theprojection I, placed above the staple, before the lip 0 will pass underor through the staple.

\Vhat I claim as new and of my invention 1. The hasp I), provided withthe lips e '0 hasp provided with a tongue having a wedgeshaped end,which, when forced through the staple, will draw the cover down upon thetub, substantially as described.

3. The combination of the tub A, having the staple f, fixed into itsside some distance from the upper edge, and the projection Z above thestaple, with the bar 0, cover B, and the hasp D, provided with thetonguej, which has the projecting lip 0, substantially as described.
